These are the project files used for the ARMUS board. It is in Altium Designer (formerly Protel) 2004 SP4 format.
Open with Robus2.prjPCB in the schematic folder.

The PROTO1 PCB is only here as a reference, as all the schematics points to PROTO2 wich is the latest version.
Also note that the layers are weirdly disposed when generating gerber files: it reverses both inner layers
Sandwich should be: bottom with ground plane - signal layers with memory routing - VCC layer - top
